Reset pin for nRF54L15

[Aurora Misic]

Hello,

I am working on a project involving the nRF54L15dk and need to connect a peripheral's reset pin to the reset functionality of the DK. However, I noticed that the reset button on the DK does not have a directly accessible pin for this purpose.

Is there a method I can use to reset my peripheral whenever the nRF54L15dk is reset?

Hello,

If you short solder bridge SB1 the reset button will do what you want:

You still need to solder a small wire directly from the PCB though.

Thank you. Could you elaborate on what "Short to connect RESET button line to nRF54L15"?

How will the reset button be connected to the dk?

Hi,

My comment was if you also need to connect this RESET pin to/from an external board, then I can't find any pin header where this is easily accessible, so you will need to solder some wire to the SB1 for instance at the same time.

It is a nice suggestion. However, I found an alternative solution that avoids hardware modifications. Instead, I implemented a software-based solution by configuring a GPIO pin on the DK to act as a reset signal for the peripheral.

Thank you!
